[0025] like Figures 1 to 3 As shown, the utility model describes an invisible door hinge, comprising a door frame 1 and an articulated swing arm 2, wherein a positioning notch 11 is provided on the side wall of the door frame 1, one end of the articulated swing arm 2 is horizontally rotatably arranged in the positioning notch 11, and a clearance gap 12 is reserved on the rear side of the door frame 1 for a decorative panel hung on the invisible door leaf to enter and exit.

[0026] In the invisible door hinge, a door cover 1 is adopted, and a positioning notch 11 is provided on the door cover 1, and one end of the articulated swing arm 2 can be horizontally rotatably arranged in the positioning notch 11. This can not only realize accurate and stable positioning by utilizing the positioning notch 11, but also make the structure of the invisible door hinge relatively simple, so as to facilitate manufacturing and reduce manufacturing costs, and ensure that the structure of the invisible door hinge has high stability and reliability. Such an invisible door hinge can reduce the overall components of the invisible door, so as to help reduce the manufacturing difficulty and cost of the invisible door. In addition, the rear side of the door cover 1 is reserved with a clearance gap 12 for the decorative panel mounted on the invisible door leaf to enter and exit, and the articulated swing arm 2 can be connected to the side wall of the invisible door, so as to ensure that the surface of the invisible door leaf is very complete, and the use of the invisible door hinge can help improve the coordination of the appearance of the invisible door leaf, so as to help improve the quality of the invisible door decoration.

[0027] like Figure 2 and Figure 3As shown, the door frame 1 is provided with a positioning hole 13 which vertically penetrates the positioning notch 11, and the hinge shaft 3 is inserted in the positioning hole 13, and the hinge shaft 3 vertically penetrates the positioning notch 11 and the hinged swing arm 2 at the same time. This can help to stably and reliably limit the hinged swing arm 2 in the positioning notch 11, thereby helping to improve the stability and reliability of the installation and positioning of the hinged swing arm 2, and further help to further improve the reliability and applicability of the invisible door hinge.

[0028] In order to realize the horizontal rotation of the articulated swing arm 2, the following structures can be adopted: First, the articulated shaft 3 is rotatably arranged in the positioning hole 13, and the articulated shaft 3 is fixedly inserted into the articulated swing arm 2. Second, the articulated shaft 3 is fixedly inserted into the positioning hole 13, and the articulated shaft 3 is relatively rotatably inserted into the articulated swing arm 2. Third, the articulated shaft 3 is rotatably arranged in the positioning hole 13, and the articulated shaft 3 is relatively rotatably inserted into the articulated swing arm 2.

[0029] like Figure 2 and Figure 3 As shown, a storage groove 131 for storing lubricant is provided on the hole wall of the positioning hole 13. An upper storage groove 131 can also be provided on the hole wall of the hole 21 for the hinge shaft 3 to pass through on the hinged swing arm 2. This can help lubricate the hinge, thereby further reducing wear and tear, and further helping to further extend the service life.

[0030] like Figure 2 and Figure 3 As shown, at least one pressing convex portion 31 is provided on the outer circumferential surface of the outer end of the articulated shaft 3, and the pressing convex portion 31 is pressed tightly against the hole wall of the positioning hole 13, and the inner end of the articulated shaft 3 is a cone. In this way, the purpose of stably installing and positioning the articulated shaft 3 can be conveniently achieved, thereby helping to improve the convenience of installing the articulated shaft 3.

[0031] like Figure 2 As shown, the pressing protrusion 31 is a strip extending axially along the hinge shaft 3, and the thickness of the pressing protrusion 31 gradually increases in the direction away from the middle of the hinge shaft 3. This not only ensures that the hinge shaft 3 is embedded very stably, but also facilitates the embedding of the hinge shaft 3, thereby helping to improve the convenience of assembly.

[0032] like Figure 1 and Figure 2 As shown, a wear-resistant washer 4 is sleeved on the hinge shaft 3 between the hinge swing arm 2 and the wall of the positioning notch 11. This can reduce the amount of wear, thereby helping to extend the service life of the invisible door hinge.

[0033] The wear-resistant gasket 4 is a wear-resistant gasket used at the hinge of existing doors and windows, which can meet the actual manufacturing and use requirements.

[0034] like Figures 1 to 3 As shown, the positioning hole 13 is vertically opened through the door cover 1. This can facilitate the positioning hole 13 and the door cover 1 to be integrally formed, thereby facilitating the convenience of manufacturing.

[0035] like Figure 1 and Figure 2 As shown, the positioning notch 11 penetrates to the rear wall of the door cover 1. This not only facilitates the opening of the positioning notch 11, but also helps to make the gap between the invisible door and the door cover 1 smaller, thereby further improving the applicability of the invisible door hinge.

[0036] like Figure 1 and Figure 2 As shown, a storage box 5 is embedded in the positioning notch 11, and the hinged swing arm 2 can swing in and out of the storage box 5. When the door cover 1 adopts an aluminum profile structure and the positioning notch 11 is cut out later, the storage box 5 can be used to cover and beautify, thereby improving the quality of the invisible door hinge, and further improving the decoration quality.

[0037] like Figure 2 and Figure 3 As shown, the door cover 1 includes a main body 14 and a convex strip 15, wherein the convex strip 15 is vertically arranged on the rear side of the main body 14, the positioning notch 11 is arranged on the side wall of the main body 14, and the positioning notch 11 penetrates the convex strip 15 backward, the hinged swing arm 2 can be horizontally rotated to connect with the convex strip 15, and the clearance gap 12 is located at the rear side of the convex strip 15. By arranging the convex strip 15 on the rear side of the main body 14 and allowing the positioning notch 11 to penetrate the convex strip 15, the hinged swing arm 2 can be horizontally rotated to connect with the convex strip 15, so that only the convex strip 15 can be exposed after installation, which can make the exposure of the door cover 1 very small, which can be reduced to 10mm, that is, the width of the convex strip 15 can be made into 10mm, so that the coordination of the invisible door can be better, which can further improve the decoration quality of the invisible door, and further improve the applicability of the invisible door hinge.

[0038] like Figure 3 , Figure 5 and Figure 6 As shown, a hanging plate 141 for hanging a wall panel is provided on the front wall of the main body 14, a positioning groove 142 for embedding a door cover 16 is provided on the rear wall of the main body 14, and a T-shaped card slot 18 for clamping a mounting code 17 is provided on the inner side wall of the door cover 1. This is conducive to making a complete invisible door structure, which can well meet the needs of actual use.

[0039] like Figure 3As shown, the main body 14 and the convex strip 15 are an integral profile structure, and the positioning hole 13 and the storage groove 131 are integrally formed on the door frame 1, which can make the door frame 1 have high structural strength and durability, thereby enabling the door frame 1 to have a very reliable positioning effect.

[0040] like Figure 2 and Figure 3 As shown, the hinged swing arm 2 includes a hinged portion 22 and a fixed portion 23. The front end of the hinged portion 22 is connected to one end of the fixed portion 23. The hinged portion 22 is placed in the positioning notch 11, and the rear end of the hinged portion 22 is horizontally rotatably arranged on the positioning notch 11. The other end of the fixed portion 23 passes out of the positioning notch 11. Such a hinged swing arm 2 is very simple and reliable, which is not only convenient for manufacturing, but also conducive to achieving a stable and accurate swinging effect, thereby being conducive to manufacturing a more reliable and applicable invisible door hinge.

[0041] After the front end of the hinged portion 22 swings out of the positioning notch 11, it can swing backwards, driving the fixed portion 23 to swing backwards, and also allowing the other end surface of the fixed portion 23 to swing to a backward state. This can well meet the opening and closing requirements, thereby meeting the actual use requirements.

[0042] like Figure 2 As shown, at least one transversely penetrating locking hole 231 is provided on the fixing portion 23. The locking hole 231 allows the threaded end of the screw to pass through and lock on the invisible door leaf, which can conveniently and stably fix the hinged swing arm 2 on the invisible door leaf, thereby helping to improve the convenience and stability of installation and positioning, and further helping to further improve the reliability and applicability of the invisible door hinge.

[0043] like Figure 2 As shown, the locking hole 231 is a countersunk hole, and the large opening of the locking hole 231 is located on an end face of the fixing portion 23, so that the screws can be hidden, thereby saving width space and facilitating the manufacture of a more compact invisible door.

[0044] like Figure 2 and Figure 3 As shown, a clamping groove 232 is provided on one end surface of the fixing portion 23, and the opening of the locking hole 231 is located in the clamping groove 232. The clamping groove 232 is for the cover strip to be inserted, so that the screw can be covered by the cover strip, which not only plays a role of covering and beautifying, but also slows down the aging speed of the screw, so as to facilitate the later disassembly and maintenance.

[0045] like Figure 3As shown, a tooth surface portion 233 is provided on the other end surface of the fixing portion 23. The tooth surface portion 233 is not only conducive to realizing the tooth-shaped pressing and positioning, but also can meet the requirement of stable adjustment of the installation position when there is an adjustment requirement, thereby helping to further improve the applicability of the invisible door hinge.

[0046] like Figure 1 and Figure 2 As shown, at least two vertically arranged side-by-side positioning notches 11 are provided on the side wall of the door frame 1, and at least one horizontally rotatable hinged swing arm 2 is provided in each positioning notch 11. In this way, the invisible door hinge can play a more stable and reliable positioning role for the invisible door leaf, thereby helping to further improve the reliability and applicability of the invisible door hinge.

[0047] When more than two articulated swing arms 2 are arranged in one positioning notch 11, the articulated swing arms 2 are arranged in a vertically stacked manner, which can meet the requirements of actual installation and use.

[0048] When multiple hinged swing arms 2 are provided, a hinge shaft 3 can be respectively inserted through the upper and lower ends of the positioning hole 13 to respectively limit the hinged swing arms 2 on the upper and lower ends of the door frame 1, thereby improving the convenience of assembly and reducing material usage.

[0050] The invisible door hinge 10 mentioned above is used on the invisible door, which not only enables the invisible door to have a very simplified structure, but also ensures that the installation and positioning of the invisible door leaf 20 is relatively stable and reliable, and can make the overall appearance of the invisible door very coordinated. It not only has high decoration quality, but also helps to reduce manufacturing difficulty and cost, and can improve the stability and reliability of the invisible door.

[0051] like Figure 5 and Figure 6 As shown, the invisible door leaf 20 is an invisible door leaf with decorative panels 201 mounted on the front and back sides. The decorative panel 201 on the rear side can swing in and out of the clearance gap 12 as the invisible door leaf 20 is opened and closed. In this way, the invisible door leaf 20 can meet the opening and closing requirements well and can ensure that the opening amount is sufficient, thereby meeting the actual use requirements very well.

[0052] like Figure 4 and Figure 7As shown, an embedding hole 202 is provided on the side wall of the invisible door leaf 20, and the other end of the fixing portion 23 is embedded in the embedding hole 202. This can further improve the reliability and stability of the assembly of the hinged swing arm 2 and the invisible door leaf 20, thereby helping to further improve the reliability of the invisible door.

[0053] like Figure 4 and Figure 7 As shown, the bottom of the embedding hole 202 is provided with a toothed portion 203 matching the toothed surface portion 233. This can more stably fix the fixing portion 23 on the invisible door leaf 20, thereby further improving the reliability of the invisible door.
